NB: If you ever want to check if a string does not contain a special character use the below formula If you do not have office365, replace the SEQUENCE function with ROW & INDIRECT functions as shown below Using a NON-Recursive LAMBDA to Clean Any Special Character.Using a Recursive LAMBDA to Clean Any Special Character.Use Power Query to Clean Any Special Character.
